GRAPHOPHONE SHAVING DEVICE.

SPECIFICATION forming part of Letters Patent No. 668,230, dated February 19, 1901.

Application filed April I, 1900.

To all whom it may concern:

Be it known that I, JOHN W. STEELE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Shaving Cylinders of Graphophones and other TalkingNlachines, of which the following is a specification.

The object of the present invention is toprovide a simple, inexpensive, and efficient device that may be attached directly to a graphophone or other talking machine in place of the recorder or reproducer and. which when so attached will shave the cylinder and leave it with a surface finished and ready for receiving another record.

The invention consists in the features of novelty that are herein described, and in order that it may be fully understood I will describe it with reference to the accompanying drawings, which are made a part of this specifieation, and in which Figure 1 is a plan view of a portion of a graphophone with my improved shaving-knife in place. Fig. 2 is a sectional elevation thereof with portions broken away. Figs. 3, 4, and 5 are enlarged detail views of the cuttingblade.

A represents the mandrel of a graphophone, and B a wax record-cylinder in place thereon. The motor for driving the mandrel is not shown.

C is the carriage, which carries the tubular connection D for the recorder or reproducer with the recording or reproducing trumpet. At one end of this tubular connection is a short sleeve or tube E, supported by a horizontal pin e, so that it is capable of free oscillation in a vertical plane. This sleeve E has in its free outer end notches disposed in a vertical plane and adapted to receive the vertical pin in the stem of the recorder or reproducer. In likemanner I make use of these notches for receiving a vertical pin E, which passes through the tubular shank of the stock of the shaving-knife G, which tubular shank is slipped over the outer end of the tubular Serial No. 11,480. (No model.)

sleeve E. The knife as a whole comprises a stock of suitable construction and weight having a vertical opening in which fits the blade H, said blade being held in place by a set-screw h. This knife when substituted for the recorder or reproducer will be free to move in a vertical plane just as the recorder or reproducer moves; but it is restrained from any lateral or sidewise movement preferably by a plate-spring I, which is secured to the knife and bears against the tubular connection D. The blade of the knife is of such length, regard being had to the diameter of the cylinder being shaved, that the cylinder contacts with the blade at a point somewhere in rear of its toe or foremost corner. Furthermore, the blade is set at a slight angle to the plane of rotation for the purpose of producing ashearing out. Its lower end is chamfered toward the rear side, and its front or cutting edge preferably has a very slight lip, which may be produced by hollow-grin .ling the front side of the blade.

Attached to the under side of the stem is a brush J ,which is designed to have contact with the cylinder for the purpose of dislodging the shavings.

Having described my invention, what I claim as new therein, and desire to secure by Letters Patent, isv 1. In a machine of the class described, the combination with a revoluble mandrel,a traveling carriage, a sleeve E, and means for horizontally pivoting the sleeve to the carriage, of a shaving-knife comprising a blade, a stock in which it is mounted, a tubularshank adapted to engage the sleeve E, and a spring carried by the knifeand engaging the carriage, substantially as set forth.

2. In a machine of the class described, the combination with a mandrel, a traveling earriage, a sleeve E provided in its outer end with vertically-disposed notches, and means for horizontally pivoting the sleeve to the carriage, of a shaving-knife comprising a blade, a stock in which it is mounted, a tubular shank adapted to engage the sleeve E, said shank carrying a vertical pin occupying the notches of the sleeve, and a spring carried by the knife and engaging the carriage, substantially as set forth.

3. In a machine of the class described, the combination with a mandrel, a traveling car riage, a sleeve E, and means for horizontally pivoting the sleeve to the carriage, of a shaving-knife comprising a blade, at stock, and

means for connecting the stock to the sleeve, said blade being beveled rearward and having to a slight lip at its forward edge, substantially as set forth. 7
